Which of the following describes the role of water in supporting the chemical reactions that occur within various life forms? It is used during photosynthesis to capture sunlight. It is critical in the process of cellular respiration. It adheres to the vascular tissue in plants. It allows sunlight to pass through it.

The correct option is;

It is used during photosynthesis to capture sunlight

Explanation:

During photosynthesis, light energy from the Sun is converted and stored in sugars as chemical energy. The Sun light energy is used in the formation of complex sugars such as glucose from the combination of water from the ground and carbon dioxide from the atmosphere while oxygen is released as the byproduct. Organisms are then able to obtain energy from the glucose as well as carbon fiber

The chemical equation for the reaction is as follows;

6CO₂     + 12H₂O + light energy → C₂H₁₂O₆  +  6O₂ + 6H₂O

Carbon,     Water,                            GLucose,  Oxygen,   Water

dioxide

It is critical in the process of ceeluar reespiration.

Explanation:

Water is critical in the process of cellular respiration, which is required for us to extract the energy we do from food. It DOES NOT capture sunlight in photosynthesis. In the first stage of photosynthesis, energy from the sun is captured to make glucose molecules, and oxygen from the water molecules is GIVEN OFF AS WASTE in the process.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
